NUT AND BOLT LOCK.

SPECIFICATION forming part of Letters Patent No. 789,470, dated May 9, 1905.

Application filed March 10, 1905. Serial No. 249,466.

To a. whom, it 771/051 concern.-

Be it known that I, SAMUEL G. WILsoN, a citizen of the United States, residing at Cassville, in the county of Huntingdon and State of Pennsylvania, have invented new and use ful Improvements in Nut and Bolt Locks, of which the following is a specification.

My invention has relation to improvements in nut and bolt locks, and is especially designed for holding and locking the nuts used on railjoints; and the object is to provide a locking device of the kind named and for the purposes mentioned which is cheaply constructed, strong and durable in use, which is readily applied in practice, and which is certain in action.

It is a further object to simplify and improve the existing art.

ith these objects in view the invention consists in the construction of parts and in the aggroupment in operative combination, as will be hereinafter fully specified and then the asserted novelty will be particularly pointed out and distinctly claimed.

1 have fully and clearly illustrated the improvements in the annexed drawings to be taken as a part of this specification.

Reference being had to the drawings, Figure 1 is a side elevation of the device as applied to the rails and the fish-plates. Fig. 2 is a vertical transverse section taken on the line 2 2 2 of Fig. 1. Fig. 3 is a detail perspective view of the flanged locking-lever withthe washer attached thereto. Fig. 4 is a detail perspective view of the other locking-lever, the outer end of which engages between the flanges of the other lever.

in the drawings similar parts appearing in different illustrations are designated by the same reference notation.

A A designate two ordinary railway-rails positioned with their ends abutting each other, as usual.

B designates one of the fish-plates or splicebars disposed against the web of the rail, being the plate to which my improvements are directly connected, and C designates the fastening bolts and nuts projected through the rail and fish-plates in the usual manner. The fishplates may be of any of the usual makes which have lodgment between the flanges of the rails. l have indicated them as consisting of a vertical plate 1, laid against the web of the rails, and a laterally-extending flange 2, resting on the base-flanges of the rails.

3 4L designate washers which are mounted on the fastening-bolts adjacent to the ends of the iish-plate and are rectangular in edge contour and are clamped against the fish-plate with their upper edges against the under side of the tread-flange of the rail and their lower edges resting on the lateral flanges of the fishplates, so that they may be securely held against turning on the bolts during the operation of the locking-levers. The washers 3 i extend inwardly, as shown, to provide sul'licient surface for the pivoted connection thereto of the locking-levers, substantially as indicated in the drawings.

5 designates one of the locking levers or bars, pivotally mounted, as at 6, on the washer or plate 4. This locking-lever is formed with a downwardly-extending piece 7 at its heel, which when the lever is in locking position contacts with the edge of the clamping-nut, and thus locks the nut lirmly against turning. The long arm of the lever 5 extends from its pivotal point a suitable distance and is so arranged that when in locked position its lower edge engages with and bears on the edges of all the fastening nuts disposed within its length, substantially as shown. At the locking end portion of the lever 5 the edges thereof are turned at right angles to the arm, as at 8, forming a seat into which the end portion of the other locking-lever snaps and locks, as indicated.

9 designates the second lockinglever pivotally mounted on the washer 3 and having at its heel a downwardly-extending piece 10 similar in construction to the part 7 on the companion locking-lever, which when the lever is turned down in locking position lodges against the locking-nut and holds it locked against the possibility of turning. The lower edge oi the locking-lever 9 is in alincment with the lower edge of the lever 5, so as to bear on the intermediate nuts and hold them locked in position. The free end of the lever 9 has a spring engagement between the flanges of the lever 5, as indicated, and has its end turned outward, as at 11, to provide means by which it may be disengaged from the seat between the flanges of the lever 5. The locking-levers are made of spring-steel, so that they will maintain themselves in alinement and also may be sprung outwardly from under the railfiange and then swung or turned upwardly on their pivotal support.

To apply and assemble the parts in practice, the washers 3 t are secured in position on the end bolts of the fish-plates, and then the lever 5 can be turned down into locking position. 1

washers, and formed with downwardly-extending end portions to lodge against the edges of the end nuts, one of said levers being formed with flanges at its free end portion and the other being adapted to engage with the other between the flanges thereon.

2. In a railway-joint, the combination with the meeting rails, the fish -plates, and the clamping-nuts, of washers mounted on the fastening-nuts, levers pivotally secured to the washers and formed with downwardly-extending end portions to lodge against the inner edges of the end nuts, one of said levers being formed with flanges at its free end portion, and the other being adapted to engage between the said flanges, said levers being disposed with their lower edges in alinement with each other, and adapted to lodge on the intermediate fastening-nuts, and also to lodge with their upper edges under the tread-flanges of the rails.

In testimony whereof Iaffix my signaturein presence of two subscribing witnesses.

SAMUEL Gr. WILSON.
